BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-theft device for an automobile opening / closing body, which is equipped with an actuator with a deadlock that can disable the unlocking of a locking device for the automobile opening / closing body.

[0002]

2. Description of the Related Art Conventionally, as an antitheft device for an automobile opening / closing body for preventing the lock device from being unlocked by a fraudulent act to achieve an antitheft effect, for example, by performing a deadlock operation from outside the vehicle with a key cylinder or a remote control switch. , Actuates the actuator with deadlock to lock all doors of the car, and prevents the lock knob connected to the door lock device for locking and unlocking from moving in the unlocking direction, unlocking by fraud Some have been designed to prevent the operation. Further, in order to further secure the anti-theft effect of the automobile, it is required to improve the anti-theft property of an opening / closing body such as a trunk lid for storing luggage in addition to the door or a back door.

[0003]

However, the lock device for the opening / closing body such as the trunk lid has a structure such as a lock knob for locking / unlocking operation provided in the passenger compartment of the door as in the door lock device. Because there is no
In order to enter the deadlock state, the deadlock actuator must be used to block the movement of the open lever that holds the meshed state so that the meshing with the striker that meshes with the lock device does not disengage. . Therefore, for example, if it is necessary to take out the luggage in the trunk before leaving the car, first open the trunk lid from inside the car, then open the driver's door and go out of the car to perform the deadlock operation. Often, when the trunk lid is open, the locking device of the trunk lid is deadlocked, and it becomes impossible to mesh with the striker.In this state, if you try to close the trunk lid by force, it will lock. Since the device may collide with the striker and cause failure, the deadlock operation must be performed after the trunk lid is closed, and the operation sequence is specified, resulting in poor operability. There is a problem.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an antitheft device for an opening / closing body for an automobile, which is improved in antitheft property and operability.

[0005]

In order to achieve the above object, the device of the present invention is connected to a locking device of an opening / closing body,
An actuator with a deadlock capable of operating in a deadlock state that prevents the lock device from unlocking by deadlock operation of the deadlock operation means from outside the vehicle, an open / close switch that detects the open / closed state of the open / close body, and an open / close switch Detects the open state of the opening / closing body and stores the deadlock operation output signal when the deadlock operation is performed, and outputs the deadlock operation output signal when the opening / closing body switch detects the closing state of the opening / closing body And a control circuit for deadlocking the deadlock actuator.

[0006]

[Operation] When the open / close body is opened and the open / close body switch detects the open state of the open / close body, a deadlock operation is performed.
The control circuit only stores that fact once, and the deadlock actuator does not immediately deadlock. After that, when the opening / closing body is closed and the opening / closing body switch detects the closed state of the opening / closing body, the actuator of the opening / closing body performs a deadlock operation and the locking device of the opening / closing body enters a deadlock state. Therefore, even when the openable body is open,
Deadlock operation is possible and operability is improved.
